There is no miracle cure that will help one lose tummy fat, mostly due to the fact that the stomach is one of the most obstinate fat holdouts for many people. The most important factor in helping one lose tummy fat is regular cardiovascular exercise.
It is easy to lose weight, but some people lose weight in different areas first or last when dieting.

I checked my BMI and it said I'm at a normal weight range, so I don't really want to lose anymore weight in case I become underweight.
The most lean athletes such as body builders have learned to fine tune their diet so their excess body fat is reduced to less than 12 percent. This time I decided to lose weight by doing what I could and would do for the rest of my life.

The problem with this is, it is not healthy to have such a low body fat percentage, especially for women.
